In this paper, we introduce a dynamic spatiotemporal autoregressive conditional heteroscedasticity (ARCH) process to describe the effects of (i) the log-squared time-lagged outcome variable, the temporal effect, (ii) the spatial lag of the log-squared outcome variable, the spatial effect, and (iii) the spatiotemporal effect on the volatility of an outcome variable. We derive a generalised method of moments (GMM) estimator based on the linear and quadratic moment conditions. We show the consistency and asymptotic normality of the GMM estimator. After studying the finite-sample performance in simulations, the model is demonstrated by analysing monthly log-returns of condominium prices in Berlin from 1995 to 2015, for which we found significant volatility spillovers.Preprint: This paper is based on the preprint arXiv:2202.13856KEYWORDS: Spatial ARCHGMMvolatility clusteringvolatilityhouse price returnslocal real-estate marketJEL: C13C23P25R31 DISCLOSURE STATEMENTNo potential conflict of interest was reported by the author(s).Notes1 Note that the matrix equation ABC=D, where D, A, B, and C are suitable matrices, can be expressed as vec(D)=(C′⊗A)vec(B), where vec(B) denotes the vectorisation of the matrix B (Abadir & Magnus, Citation2005, p. 282).

{"title":"Peer effect, political competition and eco-efficiency: evidence from city-level data in China","authors":"Xudong Chen, Bihong Huang, Yantuan Yu","doi":"10.1080/17421772.2023.2261464","DOIUrl":"https://doi.org/10.1080/17421772.2023.2261464","url":null,"abstract":"ABSTRACTThis study examines the impacts of political competition on eco-efficiency. We first develop a theoretical model in which local government officials compete against each other to maximise their own political score. We find that after an initial stage of decline, eco-efficiency eventually turns upwards, once environmental performance becomes a meaningful component of local government officials’ annual assessment. Eco-efficiency also exhibits a pattern of convergence. Lastly, the level of political competition is found to be negatively correlated with eco-efficiency. For the empirical analysis, we use a data envelopment analysis (DEA) model to compute the eco-efficiency level for 191 Chinese cities from 2003 to 2015. Our empirical evidence presents a ‘U’-shape pattern in the trend of eco-efficiency and identifies two peer effects that work in opposite directions: the incentivising effect arising from higher performing neighbours, and the disincentivising effect when a city outperforms its competitors. Both peer effects lead to convergence in eco-efficiency, and our spatial econometric modeling analysis suggests that the net peer effect is significantly positive. We also find evidence of political competition reducing eco-efficiency, as predicted in the theoretical model. Our findings are robust to alternative measures of eco-efficiency.KEYWORDS: peer effectpolitical competitioneco-efficiencyspatial analysisChinaJEL: C61C67Q56R15 DISCLOSURE STATEMENTNo potential conflict of interest was reported by the authors.Notes1 This body of research, known as the environmental Kuznets curve (EKC) literature, has been enormously influential. The work by Grossman and Krueger (Citation1995) is widely regarded as one of the earliest attempts at EKC hypotheses. For an extensive overview of theoretical studies and empirical evidence regarding EKC, see Kaika and Zervas (Citation2013).2 The term ‘eco-efficiency’ is a concept and philosophy geared toward sustainability, combining ecological and economic efficiency.3 The pollution haven hypothesis was first developed by Pethig (Citation1976) and McGuire (Citation1982), and later improved by Copeland and Taylor (Citation1994) and Levinson and Taylor (Citation2008), among others.4 For example, in its National 10th Five-Year Plan (2001–05), released in 2001, the central government for the first time added environmental protection and pollution reduction to its list of ‘national strategic goals’, and set a target to reduce pollutant discharges by 10% by the end of 2005. Under the new regulation framework, each province was assigned a specific target, and the provincial government officials were to be evaluated on, among other things, how well these targets were met. However, little improvement in environmental quality has been observed in China based on data between 1998 and 2008, because the pollution mandates imposed by the central government have triggered strategic polluting responses from the provinces (Cai et ","PeriodicalId":47008,"journal":{"name":"Spatial Economic Analysis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135142197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This matrix implies a certain structure for spatial interactions. GARCH-type models are often applied to financial data because the conditional variance, which can be translated as financial risks, is easy to interpret. However, when it comes to instantaneous/spatial interactions, the proximity between observations has to be determined. Thus, we introduce an estimation procedure for spatial GARCH models under unknown locations employing the proximity in a covariate space. We use one-year stock returns of companies listed in the Dow Jones Global Titans 50 index as an empirical illustration. Financial stability is most relevant for determining similar firms concerning stock return volatility.","PeriodicalId":47008,"journal":{"name":"Spatial Economic Analysis","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2023-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48614093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, it explores the role of cash subsidies disbursed during lockdown as well as socio-economic differences across neighbourhoods to explain their unequal response to mobility restrictions. To do so, it relies on novel data showing changes in movement at highly disaggregated spatial levels in Bogotá, before and during the first wave of the COVID-19 pandemic, matched with data on socio-economic characteristics and non-pharmaceutical interventions implemented in the period of analysis. Findings indicate that the general lockdown imposed in the city significantly reduced mobility (by about 41 percentage points). In terms of the unequal response across locations, the findings indicate that low-income areas with higher population density, informality and overcrowding reacted less to mobility restrictions. In this regard, despite government efforts, the findings indicate that cash subsidies were not sufficient to make compliance easier in low-income neighbourhoods.","PeriodicalId":47008,"journal":{"name":"Spatial Economic Analysis","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45190100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
